Owners of the new slim PSP (PSP-2000) are already taking their shiny new PSPs apart to discover what Sony has done to the new model apart from the disclosed features. It turns out that the new PSP model has a entirely new PCB version – TA-085. The new PCB version could contain further measures to prevent downgrading and possibly the installation of custom firmwares.

Most of you know that the TA-082 PCBs have been patched to allow custom firmwares to be installed, so it more that likely Sony has put in a new measure to prevent this. Aside from the upgraded UMD drive, new video-out features and firmware version 3.60, Ookm, creater of homebrew enabler (HEN), speculates that the NAND Flash and DRAM memory could both be imbedded in the new CPU chip.

It is difficult to determine what changes Sony has made to the PCB and other components without the help of Sony themselves, but we’re sure the homebrew community will figure it out soon. Updates will be posted as more information becomes available.
